More than half of ESPN’s top 100 NFL free agents for 2019 are either signed or committed to a team as the first week of the new league year closes. Now is the time when smart and/or patient teams dig in and start searching for bargains that can help them in defined roles.

Who could those bargains be? Here are 15 of the top remaining players on the open market.

Note: Baked into this list are a number of long-standing market variables. Age is a major factor (the sweet spot is 26). Quarterbacks are overvalued for obvious reasons. Teams are more desperate for pass-rushers and outside receivers than they are for safeties or veteran running backs.

Age and a long injury history will limit his value. Most recently, two shoulder injuries cost him nine games in 2018. But he had 48 sacks in six seasons with the Lions, and a team with a plan to use him situationally could receive big dividends.

Primarily working in the slot, Callahan started 10 games in 2018 and 29 in four seasons with the Bears. He would help a team that faces highly productive slot receivers. According to Pro Football Focus, opposing quarterbacks had a 78.9 passer rating when targeting Callahan in 2018, among the five lowest in the league.

Suh had a quiet season by his standards in Los Angeles, even while playing next to All-Pro defensive tackle Aaron Donald. But Suh remains remarkably durable and hasn’t missed a start in the past seven seasons. He has more years left in him as a contributing player, if not an elite one.

Injuries have limited Berry throughout his career, most notably forcing him to miss 29 games over the past two seasons and slowing what once looked like a Hall of Fame career. But he has a largely clean bill of health and could still have some gas left in the tank.

Back surgery cost him 13 regular-season games, but Jernigan returned to start the final three and both of the Eagles’ playoff games in 2018. Philadelphia declined to pick up a $11 million option, but assuming his back is healthy, Jernigan is an attractive target.

The Broncos effectively nudged Barrett out by making Bradley Chubb their top pick in the 2018 draft. But Barrett considers himself a starter, and teams can look back at his 2017 film to see it; Pro Football Focus credited him with 43 quarterback pressures that season.

Antonio Brown won big this week, but former teammate Le’Veon Bell headlined free agency’s losers. Now that the frenzy has quieted, how did everyone do?

Teddy Bridgewater is returning to New Orleans. Did the Saints get a steal? Bill Barnwell evaluates the biggest deals.

Does anyone want a 33-year-old pass-rusher who has averaged 5.6 sacks over the past four seasons? Those statistics don’t tell the whole picture, of course, and the Packers have at times used Matthews at the less visible middle linebacker position. But there is no doubt that it has been a while since Matthews was at his best.

After years of wandering, Cook put together the two most productive seasons of his career while with the Raiders in 2017 and 2018. He caught 122 passes for 1,584 yards and eight touchdowns over 30 games during that span and was named to the Pro Bowl in 2018. Age and previous durability issues could hamper his value.

Were it not for a torn ACL suffered in November, Darby would be more highly sought after. He always has managed to be around the ball in pass defense, even if his tackling has occasionally left something to be desired.

The Jaguars put a relatively light 636 touches on Yeldon’s body over the past four seasons, and he has proved productive in the passing game. But public criticism from Jaguars executive vice president Tom Coughlin late last season will give teams an extra layer to investigate.
